- String exceeding length - Getting absolute string lengthHello,
I am having a problem when inputting very long strings into a database.
The application I am writing can use different databases (thanks to
the wonders of JDBC) so this issue has been causing problems on both
Oracle and SQL Server.
Because one of the design objects was to support any JDBC compatible
database, a concern was raised about text widths. It was therefore
decided that the maximum column width for a VARCHAR would be a
configurable value. We theoretically knew that data could be more than
a single line so we introduced a sequence number to allow multiple
rows. (Don't ask me why we didn't use CLOBs instead, this is the
schema I'm stuck with.)
We now need to store base64 data in the same fields. The problem is
that in an example 4000 characters as defined by the Java string
object, its physical size is approximently 4430. This seems to be
because of the amount of mark-up involved, either in the base64 data or
possibly with the text between.
It occurs to me that while a non-ASCII value many be only a single
character in a unicode string, it is 6 characters in UTF-8. Therefore
I'm looking for a way of calculates the absolute length, rather than a
count of characters.
Is this possible or will I have to change the schema?

Any pointers or suggestions are appreciated.

- Apache Derby : create several instances.Hello.
I am using Apache derby database (Client network).
I see that when I create table it is created on an instance APP
(I don't know if instance is the correct word. sorry of my English).
I see that there are other instances (NULLID, SQLJ, SYS, etc).
Can I create an instance of my own in derby database, and how can I do that
?
(One instance may be used for repository, another for Datawarehouse, ...)
Another thing :
If I create several databases for te above reason (repository may be on
another db), how can I join them, when I am connected to database1, and want
to run a query that join both tables from database1 and database2 ?
Thanks :)

- Embedded underscoresI noticed Ruby has a convention I wish Java would implement. I think
it could be done without breaking existing code.
You simply permit the _ character to appear embedded in numeric
literals in Java source code. The lead _ would not be permitted, so
you still have no trouble telling a number apart from an identifier.
Then you might write a numeric literal like this:
2006_12_31
or
123_456_679
or
0x1234_5678
or
250_361_9093
or
1000_99
The _ is simply ignored. You use it to break the number up in
whatever way you choose to make it more readable.

By "here", I assume you mean Germany, based on what you wrote below.
There are no such laws in the US with the exception of some states that
have "blue laws" that only apply on Sundays.
Your suggestion sounds like a nightmare where you never know what is

This is why any environment worth its salt has these routines available
in a standard library. Asking people to forgo a substantial reduction
in energy use for the (supposed) convenience of computer programmers is
ridiculous. Remember that computers are not an end unto themselves,
they are tools here to serve.

- Help needed with Realm authorization and AuthenticationDear All
I'm somehow new to weblogic workshop, and i want to have a role based
security for a project.
I used XML based security in web.xml and in web-config.xml . Now i have
a problem, regarding to my project, i want for example, if role A was
logged in, to show him A in one pages of pageflow (for example
index.jsp) and if another role was logged in, not to show him the A.
I mean I want to have access to Roles in the pageFlow, and by knowing
which Role change the sequence of pageflow, do you ever reach this
problem ? any suggestions ?
I think there must be an API for accessing the realm security for
Weblogic.

- Compiling Java code using Ant within EclipseHi,
I am using Eclipse 3.0 to create a number of Java projects all located
within the same workspace. I had everything building ok but decided to
migrate to using Ant to try and manage things a bit better.
Now when I try and compile my app using Ant it does not find references
to external libraries. Now I suspect I need to specify the classpath in
the build.xml file, but is there a way of telling it to use the set of
libraries I have allready specified via Project->Properties->Java Build
Path->Libraries?
I currently have a build.xml file for each of the projects in my
workspace. Is there a way of creating a build.xml file which invokes
each of these in turn so that I can just do one big build?
Thanks for your help.

- JSTL concatenateWell.. i wanna to concatenate a string... like:
String x;

How do i do that on JSTL?
Here is my code...

I have tried without operators but it does not work. JSTL functions
also seem not to help (no concat function!)...
Any sugestions?

java-programmer, Junit: overriding original class private methods
I have a class that when run will call a private sendEfvent() method
that sends data to an external process. I would like to override that
behavior in testing and just report what is set to avoid the
complications, etc of having to use external processes during unit
testing.
I don't think I can just use an assertTrue() because I also want to
know how many times this private method is called (i.e. is it sending
the correct number of copies out)?
Is there a way I can cause Junit to stop the JRE from calling the true
sendEvent() method and instead call something in my test class??

Consider using an Interface that exposes the send event behavior.
Then your sendEfvent() method calls this strategy's send method.
During testing you can set the strategy to a mock implementation that
counts data, or better yet, exposes the message so that you can then
unit test the message contents.

- Finding BeanInfo for superclass?Hi,
I'm having a problem or a misunderstanding with BeanInfo.
I have a class Alpha, and a class Beta. Beta extends Alpha. I've
created an AlphaBeanInfo class.
The following code works fine:
BeanInfo info = Introspector.getBeanInfo(Alpha.class);
...
Problem is though when I call the following code:
BeanInfo info = Introspector.getBeanInfo(Beta.class);
...
AlphaBeanInfo is not returned, nor are any of its methods called
(verified via debugging)
Shouldn't this be returned by the Introspector? I could of course write
a BetaBeanInfo, but this seems silly to have to do this.
Any ideas/clarifications?
Many thanks,
M

- setCursor() for a ContentPanel
Joana,
I was having a similiar problem and did some searching and found the
following forum:
http://forum.java.sun.com/thread.jsp?forum=57&thread=110928
Basically, I think you need to use setCursor on the GlassPane. I used
the following code in my application and it seems to work.
Component gp = getGlassPane();
gp.setVisible(true);
gp.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
//do your computations
gp.setCursor(Cursor.getDefaultCursor());
gp.hide();
Hope this helps,
Kin Wong

- Labels and paint questions...I have an applet, here
http://www.aquaticwhirlpools.com/sean/selectMenu.html
What I need is for the select menus to have some space between
them so that I can have the orange/yellow images next to each one.
As you can see, there is a bit of one of the images next to
"by product size" and a full image next to "by model".
The space between the two "by product size" and "by shape" is
created by an empty label. The image is placed in the paint method.
The problem is that without the empty label, the menus have no space
between them, as with "by shape" and "by model". Is there any other
way to create that space... or is there a way to make the images 'paint'
on top of the labels?
Thanks for any help.

- Will MS be less evil now?I don't understand Gates. If he wants to do good deeds and be a
philanthropist, why limit such good deeds to healthcare and
education? Why not also do a good deed in the computer
industry? In this industry he is known less for his innovations
than for tactics such as sabotaging Java and cutting off
Netscape's air supply. He has done the industry and consumers
immeasurable harm, for example, by freezing the development
of web browsers. Here's an idea for Gates: Unfreeze the web
browser. Take web browsing to the next level. Start by
implementing SVG, the W3 standard for vector graphics, in IE.

- JBOSS and IPlanet setupHi,
This is a generic architectural question. I am not sure if this can
be posted at this forum.
I am using JBOSS as App server and Iplanet as WebServer and Reverse
Proxy plugin to forward all the JSP requests from Iplanet to JBOSS.
Both Web Server and App server are on different boxes.
When I request a JSP page, its coming up fine. But if that JSP page
has a 'response.sendRedirect' in it, then its failing to redirect to
the specified page. Instead its going to the webserver root.
Also, this behaviour is not consistent - meaning, sometimes it goes
through and sometimes its coming back to webserver root.
Using 'response.forward' fixed the problem.
But I do not want to use 'forward' in the web application because of
the obvious diff between 'forward' and 'redirect'. (Using the forward
doesn't change the URL and upon browser refresh, the same form gets
submitted again and again)
Are there any alternatives to fix the redirect problem?
Any help is appreciated.
Thanks,

- Displaying multiple beans in a struts formI have a list of beans that I retrieved from a database. These beans
are all of the same class. Now I want to display these beans in a

Can anyone help with this problem? Is there any sample code out there
that would show how to do this?

- Reading file lines into large ListHi all,
I have tried posting this problem a few times looking for a solution.
What I have works but is slow.
I have to read unordered data from a text file. Data A has a
one-to-many relationship with Data B, and Data B has a one-to-many
relationship with Data C . Once I find Data A, Data B and Data C could
be anywhere in the file. So I do a RandonAccessFile.seek(0) . This
needs to be repeated hundereds of times for lots of Data B and Data C
relationships.
I'd like to put the file in memory. However, I'm using Scanner and
regex to get the data. I don't think I can run Scanner on ByteBuffer
per line.
So my latest idea is to read the file per line and store it in List. So
a 10,000 line file would have a 10,000 size List. That way I could run
Scanner on the Strings in the List, and Iterate repeatably. The data in
the List would be read only.
Any advice appreciated.

I looked for your concept of "Delegation" in the only book that I have
on UML. This is by Craig Larman. Its index does not evennnnn list it.
You should expand your query to other language groups. I can do it
for you. OOP implementation questions have been asked there before

- Preverifier error in Sun Java Wireless ToolkitHi ppl,
I'm using an SDK provided by my client and building a MIDlet
application which does ApiCalls on this SDK. I copied all the jar files
from the SDK and put it into my lib folder of my MIDlet project so that
it could add it to the classpath during build. But when I build it
shows the following error:
Error preverifying class com.myClient.sdk.attributes.AttributesMaster
VERIFIER ERROR
com/myClient/sdk/attributes/AttributesMaster.addErrorElements(Lorg/w3c/dom/Document;Lorg/w3c/dom/Node;[Lcom/myClient/sdk/attributes/model/ErrorSet;)Lorg/w3c/dom/Node;:
Cannot find class org/w3c/dom/Node
If I don't use that particular jar, and the rest of the jars, it
shows this error:
Error preverifying class com.myClient.sdk.call.AddDisputeCall
java/lang/NoClassDefFoundError: com/myClient/sdk/ApiCall
I read that this is because I might be using a class library created
for the J2SE platform and hence it doesn't work for the J2ME Wireless
toolkit which uses a limited JVM and APIs. Is there any way I can merge
it into my MIDlet so that it will use it?
P.S: I'm comparatively new to J2ME :( Also i'm using the Sun Java
Wireless Toolkit 2.3 Beta. Please help...
Thanks in advance,
Sajida Abdul Salam
